Automatic Identification of Liquefaction Induced by 2021 Maduo M_w7.3 Earthquake Based on Machine Learning Methods

Remote Sensing, 2022
Rapid extraction of liquefaction induced by strong earthquakes is helpful for earthquake intensity assessment and earthquake emergency response. Supervised classification methods are potentially more accurate and do not need pre-earthquake images ...

Field relations among coseismic ground motion, water level change and liquefaction for the 1999 Chi‐Chi (M_w = 7.5) earthquake, Taiwan

Geophysical Research Letters, 2003
Field‐based, basin‐wide relations are discovered among coseismic ground motion, water‐level change and liquefaction induced by the 1999 (Mw = 7.5) Chi‐Chi earthquake, Taiwan. The relations imply thresholds of 4.4 m/s2 and 0.6 m/s in the spectral acceleration and velocity at 1 Hz, respectively, below which pore pressure does not change appreciably and ...

The survey and mapping of sand-boil landforms related to the Emilia 2012 earthquakes: preliminary results

Annals of Geophysics, 2012
Sand boils, which are also known as sand blows or sand volcanoes, are among the most common superficial effects induced by high-magnitude earthquakes. These generally occur in or close to alluvial plains when a strong earthquake (M >5) strikes on a ...
